ABB 1SDA073909R1 E2.2 W FP Iu=2000 3p HR HR

This ABB air circuit breaker is presented as the unit identified by catalog number 1SDA073909R1 and the designation E2.2. As an ACB circuit breaker with a rated current indicated as Iu=2000 A and a three‑pole configuration (3p), this low voltage air circuit breaker is intended for use where a high continuous current rating and three‑phase protection are required. The product title and designation describe the exact variant being offered rather than a family of devices.

In low‑voltage power distribution, an industrial air circuit breaker such as this ABB air circuit breaker is typically installed in switchgear, motor control centers, or distribution panels to provide manual switching and thermal/magnetic or electronic trip protection for three‑phase feeders. The presence of the E2.2 designation indicates the specific trip/setting family for this unit as shown in the product identifier, and the 3p configuration aligns it with three‑phase feeder or bus protection duties where coordinated upstream and downstream protection is required.
